mount_udfs

形式

機能説明

The mount utility attaches a udfs file system to the file system
hierarchy at the mount_point, which is the pathname of a directory. If
mount_point has any contents prior to the mount operation, these are hidden until
the file system is unmounted.

If mount is invoked with either special or mount_point as the only
arguments, mount searches /etc/vfstab to fill in the missing arguments, including the
specific_options. See mount(1M).

The udfs file system supports direct mounting of files containing the file
system as well as block devices. See mount(1M) and lofiadm(1M).

If special and mount_point are specified without any specific_options, the default is
rw.

If the directory on which a file system is to be mounted
is a symbolic link, the file system is mounted on the directory
to which the symbolic link refers, rather than on top of the
symbolic link itself.

オプション

See mount(1M) for the list of supported generic_options.

The following options are supported:

-ospecific_options

Specify udfs file system specific options in a comma-separated list with no intervening spaces. The following specific_options are available:

m

Mount the file system without making an entry in /etc/mnttab.

remount

Remount the file system as read-write. The option is used in conjunction with the rw option.

A file system mounted read-only can be remounted as read-write. This option fails if the file system is not currently mounted.

-O

Overlay mount. Allow the file system to be mounted over an existing mount point, making the underlying file system inaccessible. If a mount is attempted on a pre-existing mount point without setting this flag, the mount fails, producing the error device busy.

The device specified does not contain a udf 1.50 file system or the udfs file system module is not available.

is already mounted

The specified device is already in use.

not a block device

The device specified is not a block device. Use block device to mount.

write-protected

The device is read-only.

is corrupted. needs checking

The file system is in an inconsistent state. Run fsck.

注意事項

Copy-protected files can be stored on DVD-ROM media using Universal Disk Format
(UDF). Reading these copy-protected files is not possible as this involves an
authentication process. Unless an authentication process between the host and the drive
is completed, reading these copy-protected files after mounting and before the authentication process,
returns an error.
